Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 4-Methoxypiperidine, is researched, Molecular C6H13NO, CAS is 4045-24-3, about Nonbisphosphonate inhibitors of Plasmodium falciparum FPPS/GGPPS.Synthetic Route of C6H13NO.

A series of novel thiazole-containing amides such as I.TFA were synthesized as inhibitors of Plasmodium falciparum farnesyldiphosphate synthase (PfFPPS) and geranylgeranyldiphosphate synthase (PfGGPPS). A structure-activity relationship study of these compounds led to the identification of potent and selective PfFPPS/GGPPS inhibitors with good in vitro ADME profiles. The most promising candidate mols. were progressed to mouse in vivo PK studies and demonstrated adequate free drug exposure to warrant further investigation.

The hydroxy ester I (R = H, R1 = OH), prepared from L-ascorbic acid by sequential treatment with acetone and AcCl, 30% H2O2 and CaCO3, and Me2SO4, was treated with MeSO2Cl and pyridine in CH2Cl2 to give 90% I (R = H, R1 = MeSO3), which, when heated at 85° with LiCl in DMF furnished a mixture of the erythro and threo chloro esters I (R = Cl, R1 = H; R = H, R1 = Cl) (II). Upon hydrogenolysis with 10% Pd/C in the presence of Et3N, II yielded the ester I (R = R1 = H), which was treated with dilute HCl giving a nearly quant. yield of hydroxylactone III. The (S)-enantiomer was analogously prepd from D-isoascorbic acid.

The preparation of enantiomerically pure β,γ-epoxy esters was achieved by chemoselective opening of β-hydroxybutanolides with Me3SiI followed by cyclization of the resulting iodohydrins with Ag2O. The reaction of these epoxy esters with lithio- or magnesiocuprates afforded stereochemically pure α-substituted-β-hydroxy esters.

(S)-4-Chloro-3-hydroxybutyrate (CHB) is essential for the synthesis of biol. and pharmacol. important compounds Rhizobium sp. DS-S-51 isolated from soil samples showed hydrolytic activity toward (R)-CHB in the racemate to (R)-3-hydroxy-γ-butyrolactone (HL) under a simple composition of the reaction. Residual (S)-CHB was obtained with high optical purity. The gene encoding the enzyme concerned, designated CHB hydrolase, was isolated from DS-S-51, and the gene was highly expressed in Escherichia coli JM109. When the resolution of racemic Me CHB (CHBM) as a substrate was performed using this recombinant cell, JM109 (pKK-R1), the hydrolytic activity was found to be 40-fold greater than that of DS-S-51, and the maximum concentration of the substrate added increased 2-fold. Moreover, (R)-HL was also obtained without decreasing the optical purity compared with that when (R)-CHBM was used as a substrate.

Category: pyrrolines. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 4-Chloro-2-fluoropyridine, is researched, Molecular C5H3ClFN, CAS is 34941-92-9, about Total Synthesis of (-)-Maximiscin. Author is McClymont, Kyle S.; Wang, Feng-Yuan; Minakar, Amin; Baran, Phil S..

A short, enantioselective synthesis of (-)-maximiscin (I), a structurally intriguing metabolite of mixed biosynthetic origin, is reported. A retrosynthetic anal. predicated on maximizing ideality and efficiency led to several unusual disconnections and tactics. Formation of the central highly oxidized pyridone ring through a convergent coupling at the end of the synthesis simplified the route considerably. The requisite building blocks could be prepared from feedstock materials (derived from shikimate and mesitylene). Strategies rooted in hidden symmetry recognition, C-H functionalization, and radical retrosynthesis played key roles in developing this concise route.
